Measured tools (8)

• list_sheets read-only

  Discover sheet names and used dimensions before reading or editing a WorkPaper. Returns metadata only; use read_range or read_cell for values.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• read_range read-only

  Read calculated values plus serialized formulas/inputs for an A1 range. Use for audit readback after edits; use read_cell for one address.

  Parameters:

  • range (required) — string — A1 range such as Summary!A1:B5. If omitted from the range, pass sheetName separately.
  • sheetName — string — Default sheet name when range omits a sheet name, for example Summary.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• read_cell read-only

  Read one cell with calculated value, display text, formula text, formula diagnostics, and serialized content. Use after set_cell_contents to verify readback.

  Parameters:

  • sheetName (required) — string — Existing sheet name.
  • address (required) — string — Single A1 cell address such as B3.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• set_cell_contents

  Write raw content to one cell and recalculate dependents in memory only. Start with --writable when the edit should persist to JSON.

  Parameters:

  • sheetName (required) — string — Existing sheet name, for example Inputs.
  • address (required) — string — Single A1 cell address such as B3. Ranges are not accepted.
  • value (required) — string — Raw cell content. Formula strings must start with =; plain strings are stored as literals. Strict MCP hosts such as Semantic Kernel require a single parameter type, so pass evaluated numbers/booleans as formulas such as =0.4 or =TRUE(). The server still accepts JSON number, boolean, or null arguments from clients that support them.

  Hints: read-only no · destructive no · idempotent yes · open-world no

• set_cell_contents_and_readback

  Write raw content to one cell, recalculate dependents, read a dependent range in the same tool call, and return persistence proof. Use this for stateless MCP clients such as hosted Open WebUI integrations.

  Parameters:

  • sheetName (required) — string — Existing sheet name for the cell to edit, for example Inputs.
  • address (required) — string — Single A1 cell address to edit, such as B3. Ranges are not accepted.
  • value (required) — string — Raw cell content. Formula strings must start with =; plain strings are stored as literals. Strict MCP hosts require a single parameter type, so pass evaluated numbers/booleans as formulas such as =0.4 or =TRUE(). The server still accepts JSON number, boolean, or null arguments from clients that support them.
  • readbackRange (required) — string — Dependent A1 range to read before and after the edit, for example Summary!A1:B5.
  • readbackSheetName — string — Default sheet name when readbackRange omits a sheet name.

  Hints: read-only no · destructive no · idempotent yes · open-world no

• get_cell_display_value read-only

  Return the formatted display string for one cell. Use when an agent needs what a user would see, not the raw numeric value.

  Parameters:

  • sheetName (required) — string — Existing sheet name.
  • address (required) — string — Single A1 cell address such as B3.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• export_workpaper_document read-only

  Export the current WorkPaper JSON document for persistence, review, or handoff to another agent. Does not write files by itself.

  Parameters:

  • includeConfig — boolean — Include workbook configuration metadata in the exported JSON. Defaults to true.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• validate_formula read-only

  Validate formula syntax with the WorkPaper parser before writing it to a cell. This checks syntax only; use set_cell_contents plus readback to evaluate.

  Parameters:

  • formula (required) — string — Formula string including the leading =, for example =SUM(Inputs!B2:B4).
